GASKET.

Patented July 18, 1916.

Application filed flctoberll, 1913. Serial No. 794,590.

To all whom it may concern:

Be it known that I, LEONHARD BAUROTH,

a citizen of the United States, and a resident of Toledo, in the countyof Lucas and State of Ohio, have invented a certain new and usefulGasket; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the characters ofreference marked thereon,- which forms a part of this specification.

' This invention relates particularly to gaskets, but is notrestrictedto such use as it may be used in any connection for which itmay be adapted or appropriate.

Considerable difficulty has been experienced in the use of casks,barrels or the like due to the gaskets commonly employed in connectionwith the bungs thereof becoming loose, misshaped and cut, and inconsequence dropping from the bung or permitting leakage around thesame.

The object of my invention is the provision of a simple and inexpensivegasket of this character, which is designed to obviate the difiicultiesabove noted and to materially prolong the life and stability of suchgaskets.

The invention is fully described in the following specification, andwhile, in its broader aspect, it is capable of embodiment in numerousforms, a preferred embodiment thereof is illustrated in the accompanyingdrawings, in which,

Figure 1 is a perspective view of a cask equipped with. my improvedgasket. Fig. 2 is an enlarged central section of the bung receiving partthereof and gasket with the bung in full in screwed-home positiontherein, and Fig. 3 is an enlarged section of a portion of the gasket asit substantially appears before use.

Referring to the drawings, 1 designates a cask, barrel or other form ofcontainer having a bung-receiving flange 2 on a part thereof, which, inthe present instance, 1s internally threaded to receive a threaded bungor plug member 3. It is customary to pro vide the bung or plug member 3at its Outer end with a transversely extending periph: eral flange 4 foroverlapping and extending transversely beyond the Outer end of theflange 2, and to provide an annular groove 5 at the base of the threadedportion of the bung with the inner side of the flange 4 formmg one wallthereof.

The gasket forming my invention com prises the body part 6, which isusually, but not necessarily, of annular or ring form, and may be of anysuitable non-metallic gasket forming material, and the edge binding 7 ofsheet metal or other suitable material. The binding is preferably madeU-shape in cross-section, as shown, to receive the Outer edge portion ofthe part 6, and has its loop portlon abutting against the Outerperipheral edge of the body part to resist an outward or radialexpansion of such part, andits leg portions embracing opposite sides ofthe body part to retain the binding in clamped engagement therewith.

The closely clamping of the binding 7 onto the outer edge portion of theyielding gasket material 6 causes a swelling of such material adjacentto the'binding, substantially as shown at 8. The swelling of the gasketat 8 renders it thicker at such point than the binding 7, so that aconsiderable compressing force may be exerted on the body part 6 of thegasket before pressure is brought to bear on the binding. When thegasket is first applied to the bung or plug member its opening ispreferably of suitable size to be forced over the threaded part Of theplug to place it in register with the groove 5 thereof. Upon ascrewing-home of the plug within the flange 2 the gasket material.within the point of gripping of the flanges 2 and 4 is compressed andflattened.

As the body part of the gasket expands Out wardly due to the resistanceof themarginal binding strip 7 to such expansion the body part is causedto contract within and tofill the groove 5, thus effecting a tightfitting of the gasket around the plug portion of the bung. It is alsoevident that the binding serves to prevent an enlarging of the gasketunder varying conditions of use, and consequently materially prolongsthe life thereof.

I Wish it understood that my invention is not limited to any specificconstruction but contemplates broadly the provision of a gasket havingan edge thereof provided with an unyielding binding to permit the gasketproper to radially expand or contract in one direction only relative toits center when subjected to a flattening pressure.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is,

A gasket having a non-metallic body part and an endless U-shapednon-expansible metallic binding for the outer edge portion of said part,the exposed portion of the body part being of greater thickness than thebinding When mounted on the edge 10 thereof, whereby a considerablecompressing force may be exerted on the exposed portion of the body partbefore pressure is brought to bear on the binding.

In testimony whereof, I have hereunto signed my name to thisspecification in the 1 presence of tWo subscribing Witnesses.

LEONHARD BAUROTH;
